Write Protection

Advanced forensic-grade hardware write protection for complete data integrity.

IODD provides robust write protection that can be applied globally to the entire device or individually to specific virtual drives. This ensures your data remains untampered when connected to external systems.

[!CAUTION] Emergency Security Connection When connecting the IODD to an unverified or insecure system, always press and hold the [3] key while plugging it in. This forces the device into Write-Protect mode immediately, preventing any malware or unauthorized system from modifying your data.
